That was Kyle Shanahan’s reaction Monday night after a lost-and-found misadventure at the Super Bowl.

At the end of the Atlanta Falcons' media session, the team's star offensive coordinator — soon to become the San Francisco 49ers' new head coach — discovered that his backpack was nowhere to be found. Gone — the contents inside apparently including the team's gameplan for Super Bowl LI.

As the drama unfolded, Shanahan paced Minute Maid Park, looking for clues. A Falcons security agent, meanwhile, searched through an unattended backpack on the floor.
